It is understood that topsoil and other overburden soils must be handled and stored separately. Topsoil will be removed from the area that is scheduled for mining. That topsoil will be placed in storage in the area in which mining activities have most recently concluded. If that area is no longer to be used for gravel storage or any other mining activity, the topsoil will be placed lcE~~ on the area in an 8 inch fo 12 inch lens? It is not anticipated that any topsoil will remain in storage for an extended period of time since reclamation, including backfilling, grading and S/,~i.w„ , Z ; ~~ topsoil replacement, will occur soon after the completion of mining in a given area. C~ i k The exception to this is that for the final segment of Phase 5. Enough topsoil to adequately reclaim the last stage of mining will need to be stored. This is depicted on the Mining Plan Map. It is anticipated that an additional 3 acres to 5 aces will be affected each year. Consequently, any topsoil placed in storage will be placed on the floor of the pit nearby where it will shortly be used for reclamation. It seems difficult to accurately represent this procedure on a map, and show it throughout the course of the mine in each phase. Please refer to the response to Exhibit E-Reclamation Plan, item number 2. The available quantity of topsoil has been questioned through objector's comments and the Division's concerns. The soil study that was referenced above was conducted to determine the quantity of topsoil that is available, and to calculate the balance between what is actually available, and the quantity that will be required to reclaim the entire site. The currently available topsoil that is now on site can be separated into two categories, topsoil still in place, and topsoil in stockpile. Of the 84.3 acres that comprise the site, 76.7 acres will be affected by mining, and therefore require reclamation. Of the area to be affected by mining, 14.1 acres in Phase 1 have already been mined . That leaves 62.6 acres remaining that have not yet been disturbed. The following calculations are offered as evidence in the soil-balance study. A. The average depth of 1.16 feet of topsoil will yield 1871.47 cubic yards of topsoil per acre. B. At ] 871.47 cubic yards per acre, 62.6 acres will yield 117,154 cubic yards of topsoil. C. Seven topsoillstockpiles currently on site consist of 9,029 cubic yards. D. The total ofthe topsoil stockpiles on site and the available topsoil on the area to be mined is 126.183 cubic yards. E. Because of additional surface area created by the slopes around the perimeter of the site, the total surface area requiring topsoil amounts to 78.7 acres. ~{ p 1 ~ ~ ~ I SyI v4~F.
